MINE APPARATUS.

Application filed May 14, 1918.

To all whom it may concern:

Be it known that I, ALnnn'r BUCEY, a citizen of the United States,residing at Bowerstown, in the county of Harrison and State of Ohio,have invented new and useful Improvements in Mine Apparatus, of whichthe following is a specification.

This invention relates to an apparatus for handling cars in a mine andmore particularly to an apparatus for feeding cars onto and off of thecage and has for its primary object to simplify and thereby reduce theexpense of an apparatus of this character.

An object of the invention is to provide an apparatus in which onlythree stops can accomplish the work of the usual four stops necessary inthe apparatuses now in use.

Another object of the invention is to provide mechanism that may,without changes, be attached to the top surface of a cage or the undersurface depending upon which is the most advantageous in practice whenused on the different type cages now in use.

Besides the above my invention is distinguished in the use of cagemechanism and trackway mechanism of substantially the same constructionfor feeding cars onto the cage and off the cage.

With these and other objects in view the invention will be betterunderstood from the following detailed description taken in connectionwith the accompanying drawings wherein:

Figure 1 is a top plan view of a cage showing my invention appliedthereto.

Fig. 2 is a longitudinal sectional view.

Fig. 3 is a detail view of a portion of the link mechanism. Fig. 4 is asectional view through a rail showing the rear stop in elevation. Fig. 5is a detailed view of the car actuated lever. Fig. 6 is a top plan viewof the trackway mechanism. Fig. 7 is a detailed view of one element ofthe clutch. Fig. 8 is a detailed view of one of the stops.

Again referring to the drawings the numeral l designates a shaftconsisting of two parts 2 and 3, both mounted for rotatable movement inbearings A while part 3 is also mounted for longitudinal slidingmovements. One end of the shaft in this particular instance the part 2,has connected thereto a crank arm 5 adapted to strike a stationary arm 6Within the mine when the cage 7 reaches predetermined positions.

A clutch device 8 is arranged to normally connect the parts 2 and 3together and in Specification of Letters Patent.

Serial No. 234,462.

each of the parts 2 and 8 is a coil expansion spring 12 having one endfixed to a collar 13 on the part and the other end fixed to one of thebearings 1. By this arrangement it will be seen that one of the coilexpansion springs 12 performs a dual function of forcing one part towardthe other part and besides both springs return the parts to normalposition, when partly rotated by the crank arm 5 striking the arm 6. Theexpansible action of the spring 12 normally holds the clutch elements inengagement with each other so that the parts will move as a unit whenpressure is applied upon the crank arm 5. At certain times it isnecessary that the clutch be rendered inoperative for accomplishing anoperation hereinafter described. For this purpose I provide a caractuated lever 13 pivoted to a bracket 15 and further pivotallyconnected to one end of a link 16 the other end of which is forked asindicated at 17 and arranged behind the collar 13*. For the purpose ofabsorbing shock a spring 18 is arranged between the fork 17 and theadjacent bearing 1. As far as I have proceeded it will be seen that whenthe crank arm 5 strikes the arm 6 both parts of the shaft will berotated as a unit; whereas upon a car axle striking the lever 14.: thepart 8 will he slid longitudinally for disengaging the clutch elements,thereby allowing the part 3 to rotate independently of the part 2 by thetorsional action of the spring 12. Projecting from the element 8 arearms 19. Pivotally connected to the rails are stops 20 and 21.

The stop 20 is connected to the arm 19 by a link 22 and yieldably forcedin a predetermined direction by a sprin 23. The stop 21 is connected toa second pivoted lever 24: by a link 25. The lever 24 is also pivotallycon: nected by a link 26 to the arm 19. To complete the cage mechanism Iprovide a third pivoted stop 27 normally forced to an operative positionby a leaf spring 28. This stop 27 is provided with a cam surface 29 soas to be automatically forced to an inoperative position in the passageof a car.

The track-way mechanism 30 is identical to that described with thefollowing exceptions;

The crank arm 31 is constructed to be engaged by a descending cage. Onepart of the shaft has connected thereto a weight 32 normally holding theparts in predetermined positions. As an improvement over the cagemechanism the spring 33 of the trackway mechanism consists of two parts3% and 35 each acting against a bearing 86 and a collar 37 fixed to theshaft. Working between the collars 37 is the forked end 38 of a link 35.The remaining parts of the trackway mechanism are identical to the cagemechanism with the exception that the element 40 of the clutch device isprovided with diametrically arranged ears ll pivoted to links that aredirectly connected to the stops as.

From the foregoing description taken in connection with the drawings itshould be apparent that I provide a simple mechanism of substantialconstruction in which the parts are so arranged and constructed that theoperation of the apparatus is assured,

with a minimum number of parts.

It is of course to be understood that the mechanism may be constructedin various other ways than that shown, which is illustrated in thesimplest form, all mechanical details being eliminated. Therefore I donot desire to be limited to the exact showing exact showing except asset forth in the claim appended.

Having described my invention, what I claim is:

A mine car handling apparatus comprisinga two part shaft, a crankrigidly connected to one end of the shaft, a clutch device consisting oftwo elements rigidly connected respectively to said parts, said partsbeing slidably related, car stopping and releasing means having aconnection with one of the elements, a. collar fixed upon one of saidparts, a pair of coil springs mounted on said shaft and abutting astationary support, one of said springs being capable of returning saidshaft part which it is associated with to normal position, and a caroperated pivoted lever engaging said collar between said springs for thepurpose set forth.

In testimony whereof I afliX my signature.
